Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021862, here are decompositions:

13 + 1021849 = 1021862
31 + 1021831 = 1021862
103 + 1021759 = 1021862
109 + 1021753 = 1021862
151 + 1021711 = 1021862
199 + 1021663 = 1021862
211 + 1021651 = 1021862
241 + 1021621 = 1021862

Showing the first eight; more decompositions exist.
